WL-168 When redeeming a Registration Code in the shopping cart, the user should be redirect to the Registration Code Redemption page

Kindly review the changes for WL-168

Thanks
Note to any other reviewers, dropping column is approved. We are no longer tracking on which shopping cart a Registration Code has been redeemed on as we are changing the UX to jump to the new Registration Code redeem flows.
